What is Tumor Resection?
Tumor resection is the surgical removal of brain tumors, whether benign or malignant. The goal of resection is to eliminate as much of the tumor as possible while preserving critical brain functions. Depending on the tumor’s size, location, and type, a combination of advanced neurosurgical techniques may be used to ensure the safest and most effective outcome.
At California Neurosurgical Specialists, Dr. Arnau Benet — the best brain tumor surgeon in Los Angeles — customizes each surgery to the patient’s unique condition. Using state-of-the-art imaging, neuronavigation, and microsurgical precision, he maximizes tumor removal while protecting vital neurological structures.

How Do I Know if I Need Brain Tumor Resection?
Brain tumor symptoms vary based on size and location but may include:
Persistent headaches that worsen over time
Seizures or unexplained convulsions
Difficulty with balance, coordination, or walking
Memory loss, confusion, or cognitive decline
Vision, speech, or hearing impairments
Weakness or numbness in the arms or legs
Personality or behavioral changes
If you are experiencing these symptoms, an MRI or CT scan can help determine if a tumor is present and whether surgical resection is the best treatment option.

What to Expect During Brain Tumor Surgery
Tumor resection is a complex procedure that requires expertise, precision, and cutting-edge technology. Dr. Benet follows a meticulous approach to ensure the best possible outcome:
1.
Pre-Surgical Preparation
Comprehensive Evaluation: Advanced imaging (MRI, fMRI, and CT scans) maps the tumor and surrounding brain structures.
Neurosurgical Planning: Dr. Benet develops a precise surgical strategy using neuronavigation and intraoperative imaging.
Pre-Operative Consultation: The procedure, risks, benefits, and expected recovery are thoroughly discussed.
2.
During Surgery
Anesthesia & Monitoring: The procedure is performed under general anesthesia, with real-time monitoring of brain activity and vital signs.
Intraoperative Mapping: If necessary, awake brain mapping and neurophysiological monitoring help protect key brain functions.
Tumor Resection: Dr. Benet employs advanced microsurgical techniques, fluorescence-guided imaging, and intraoperative MRI to safely remove as much of the tumor as possible.
Intraoperative Imaging: Real-time imaging ensures maximum tumor removal while minimizing risks.
3.
Post-Surgical Recovery
ICU Monitoring: Patients are closely observed for the first 24-48 hours after surgery.
Neurological Assessment: Cognitive and motor function evaluations help determine rehabilitation needs.
Pain & Symptom Management: Medications and steroid therapy help control discomfort and swelling.
Hospital Stay & Follow-Up: Most patients stay for several days before discharge. Follow-up imaging and, if necessary, additional treatments like radiation or chemotherapy are planned.

Brain Tumor Resection Volume & Quality Metrics
Brain tumor resection is performed to remove as much tumor as safely possible while protecting critical brain function. Across residency training and independent private practice, Dr. Benet has performed approximately 219 brain tumor resections, supported by approximately 514 craniotomies (all types). In independent practice, he reports a surgical complication rate (cumulative through December 2025) below 2% and a 98% satisfaction rate with surgical outcomes (all cases aggregate). Each case is evaluated individually, with surgical planning tailored to tumor type, location, and the safest path to durable treatment.
Frequently asked Questions
FAQs About Brain Tumor Resection
Is brain tumor resection always necessary?
a.
Not all brain tumors require surgery. Treatment depends on the tumor’s type, size, and location. Some slow-growing tumors may be monitored, while aggressive or symptomatic tumors often require resection.
What are the risks of brain tumor surgery?
a.
Risks depend on tumor location and patient health but may include infection, bleeding, or temporary neurological deficits. Dr. Benet uses the latest surgical advancements to minimize risks and optimize recovery.
Will I need additional treatment after surgery?
a.
If the tumor is malignant or cannot be entirely removed, additional treatments such as radiation therapy or chemotherapy may be necessary.
